Using the aid of a clone, the two Kakashi each perform the Lightning Cutter technique on opposite hands. Connecting their techniques together, they form a chain of lightning between themselves that was powerful enough to slice through a tailed beasts' chakra arms with relative ease. Kakashi was also able to wrap the lightning around a target, thus effectively restraining its movements, as shown against the Demonic Statue of the Outer Path.[2]

Trivia

When written as '雷電', Raiden means "thunder and lightning".

With the "-sama" suffix added, Raiden is another name for the Shintō god of lightning, Raijin (雷神).
